TCC was developed under a partnership between the National Crime Prevention Council and Street Law, Inc, funded by the Office of Juvenile Justice and Delinquency Prevention (OJJDP). In a TCC program, school teachers and other staff instruct youth in the effects of crime, how to recognize and prevent crime, how to report crime, how to be a good witness, and how to help crime victims. Just over half a million youth in 40 States have participated in TCC since it began in 1985. TCC engages youth in various types of projects, including designing billboards on crime prevention, conducting workshops on date rape, administering surveys on violence, cleaning up neighborhoods, and organizing fundraisers for the homeless. Examples are provided of a few TCC programs that have had a significant impact on youth. These examples come from a middle school in San Antonio, TX; a high school in Birmingham, AL; and a teen center in Atlanta, GA.
